AEC-Q200-qualified Inductors and Magnetic Components

This article discusses AEC-Q200 qualified inductors and the implications these and other passive components have on vehicle system performance.

What is AEC?

The Automotive Electronics Council (AEC) is a global council that includes many Sustaining Member automotive companies including Autoliv, Bose Corporation, Continental Corporation, Cummins, Delphi Corporation, Denso International America, Gentex Corporation, Harman, Hella, John Deere Electronics Solutions (Phoenix International), Kostal Automotive, Lear Corporation, Magna Electronics, Sirius XM, Valeo, Visteon Corporation, ZF, TRW Automotive, and other Technical, Associate, and Guest Members.

The AEC council includes two committees:

  1. The Quality Systems Committee and the
  2. Component Technical Committee
The AEC Component Technical Committee has created stringent test standard specifications for high quality electronic components used in automotive applications. Components qualified to these specifications are suitable for high-temperature automotive environments.

The complete AEC-Q200 REV D (June 1, 2010) base pdf document "Stress Test Qualification for Passive Components" can be downloaded free-of-charge from the AEC Council website.

What is an AEC-Q200 inductor?

An AEC-Q200 inductor has passed the environmental stress testing requirements of the AEC-Q200 global standard. This standard tests the ability of passive electronic components to withstand the temperature and physical stresses of automotive environments. Automotive industry companies require the use of AEC-Q200 qualified components. Selecting AEC-Q200 qualified inductors eliminates the need for additional component qualification testing.

What are the temperature ranges covered by AEC-Q200?

Stress test qualification temperature ranges established by the AEC-Q200 standard are categorized into five grades (0 - 4), as shown below:

Grade Temperature Range Typical Application
0 −50°C to +150°C All automotive applications
1 −40°C to +125°C Most under-hood applications
2 −40°C to +105°C Hot spots within the passenger compartment
3 −40°C to +85°C Most passenger compartment
4 0°C to +70°C Non-automotive commercial / industrial


What AEC-Q200 tests apply to Coilcraft off-the-shelf inductors?

Table 5 (Pages 28 and 29) of AEC-Q200 Rev D (June 1, 2010) defines the test methods and additional requirements for magnetics, including inductors and transformers. These tests include a variety of methods to test the component's ability to withstand severe conditions, including:

Representative component samples are also measured to verify that the physical dimensions comply with the datasheet specifications. In addition, they are inspected visually for construction, marking, and workmanship, and the electrical parameters are measured pre- and post-stress testing to verify conformity to specifications. This rigorous battery of tests assures that the AEC-Q200 qualified inductors are capable of handling the harsh conditions of the automotive environment.

What types of AEC-Q200 inductors does Coilcraft manufacture?

Do I need to use AEC-Q200 inductors for my application?

Coilcraft has a variety of tools to assist in finding AEC-Q200 qualified inductors and other products for your application.

While the intention of AEC-Q200 is to ensure a high level of component ruggedness for automotive use, it is not generally specified for non-automotive applications. Other inductors may be available for non-automotive applications. You can use the tools listed above to identify the inductive component that makes the best sense for your application. While not meeting all AEC-Q200 qualification requirements, these products are qualified to meet Coilcraft's commercial qualification requirements. Contact Coilcraft Technical Support to discuss your commercial or industrial application requirements.

Need higher or lower temperature ratings or ruggedized products for high-reliability applications?

Coilcraft's Critical Products & Services group offers power inductors, RF chip inductors and air core inductors rated from −60°C to 155°C and 200°C ambient.
